High-Output Car Tweeter

The DS18 PRO-TW920 is a 1.4-inch neodymium super bullet tweeter designed for car audio enthusiasts seeking high-frequency clarity at high volume levels. It handles 160 watts RMS and 320 watts peak power with a 4-ohm impedance and 106dB sensitivity for efficient output. Sold as a single unit, it targets builders adding crisp treble to custom front-stage or competition systems.

Thermal and Power Behaviour

The 1.4-inch voice coil uses KSV former material and CCAR winding to manage heat during extended high-power playback. Neodymium magnet construction keeps the motor lightweight while maintaining strong flux density for consistent performance. The included 4.7uF/50v bass blocker filter protects the diaphragm from damaging low-frequency energy. Aluminium body and CNC bullet materials aid passive heat dissipation during normal use.

Build Integration

The tweeter features an adjustable surface mount with a 2-inch front baffle cutout and a mounting depth range of 52 to 70 millimetres. Overall diameter measures 69.2 millimetres and depth is 76.6 millimetres, fitting tight dashboard or pillar locations. The 4-ohm nominal impedance matches standard car audio amplifiers and crossovers. A recommended 2kHz high-pass crossover point ensures proper frequency blending with midrange drivers.

Questions about this item

How do I mount the PRO-TW920 tweeter and what cut-out size is required?

Drill a 2-inch (51.8 mm) hole in the baffle and use the adjustable surface mount; the mounting depth can be set between 52 mm and 70 mm.

Does the included 4.7 µF bass-blocker capacitor ever need replacement?

The 4.7 µF/50 V capacitor is a passive component with no moving parts and does not require scheduled replacement under normal use.

What thermal limit appears first when running the tweeter at high output for long periods?

The 1.4-inch CCAR voice coil on a KSV former will reach its thermal limit before the neodymium magnet or titanium diaphragm.
